Conserving agrobiodiversity to adapt crops to climate change: inauguration of two major facilities

PRESS RELEASE - On 6 October in Montpellier, CIRAD, INRAE, IRD and Institut Agro – alongside representatives of the Prefecture and the Occitanie Region, and Michaël Delafosse, President of Montpellier Méditerranée Métropole and Mayor of Montpellier – inaugurated two facilities that will play a major role in the adaptation of crops to climate change. The first, ARCAD, a genetic resources centre, contributes to conserving Mediterranean and tropical crop diversity, which is essential to plant breeding in the context of the agroecological transition. The second, the AbioPhen greenhouses, simulate future climate conditions.

ARCAD provides Montpellier with a world-class centre dedicated to the conservation and study of Mediterranean and tropical crop genetic resources. The Agropolis Resource Centre for Crop Conservation, Adaptation and Diversity (ARCAD), hosted by INRAE, brings together the main collections of crop genetic resources from CIRAD, IRD and INRAE in Montpellier. ARCAD is the first French crop conservation “bank”, and holds some 50 000 samples (vines, maize, Medicagol, sorghum, durum wheat, rice, millet, cotton, fonio, groundnuts, cocoa, coffee, forest trees, etc.), in the form of seeds or in vitro plants.

ARCAD: conserving and managing the genetic diversity of tropical and Mediterranean plants

The centre is built in the form of an H around the seed conservation platform, at the heart of which is a robot stacker that is the only one in Europe. This is surrounded by three technical platforms (genotyping-sequencing, seed phenotyping, cryoconservation) equipped with the latest technologies to conserve and study this genetic diversity.

Studying the diversity of crops and their wild relatives is essential in a context of globalisation and global change. Certain heirloom or wild varieties, which are sometimes endangered, may be less sensitive to climate conditions or to the emerging diseases and plant pests that are spreading throughout the world. They can also be used as parents of new varieties that are better suited to these new contexts.

Moreover, growing a range of different species and varieties is a guarantee of resilience, especially for family farms, which provide more than half of the world’s agricultural production. This contributes to food and nutrition security. Finally, conserving, studying and disseminating this diversity by articulating the different modes of conservation in a complementary manner (in the field with farmers or in centres such as ARCAD) and by recognising the different processes and actors involved in the creation of diversity (farmers, researchers, plant breeders) are key to successful food and agroecological transitions at the global level.

AbioPhen: testing varieties adapted to future climate conditions

CIRAD’s AbioPhen greenhouses, which are close to the ARCAD centre, are aimed at furthering research on adaptation to climate change in certain crops, such as rice, and subsequently examining in detail the mechanisms at work and identifying associated genetic traits. Climate conditions can all be controlled (light, temperature, humidity) and CO2 can be increased up to four times the atmospheric level, enabling the greenhouses to simulate future climates: higher temperatures and atmospheric CO2 levels, or drier air. These high-tech greenhouses will be used to study the behaviour of new varieties, resulting from controlled crosses or from new associations of varieties or species, in the climate conditions of the coming decades.

Two facilities financed by the Contrat de Plan Etat-Région (CPER 2015-2020)

The ARCAD centre (Agropolis Resource Centre for Crop Conservation, Adaptation and Diversity) was built in the framework of the Contrat de Plan Etat-Région for a total amount of 10.4 million euros, with financing provided by the Regional Council (6.5 million euros and provision of land) and Montpellier Méditerranée Métropole (1 million euros), and co-financing provided by partner scientific institutes (2.9 million euros): INRAE, CIRAD, Institut Agro and IRD. Bringing together 13 research units, around 100 scientists specialising in genetic resources, as well as training and hospitality facilities (in particular for the countries of the global South), this new centre strengthens the scientific dynamics of the “Feed” pillar of the MUSE I-SITE (University of Montpellier) and its international visibility.

The AbioPhen greenhouses were financed by the Contrat de Plan Etat-Région (3 million euros), with 1.3 million euros provided by the Regional Council and 1 million euros by the French State) in the context of RéSEM (Montpellier network of experimental greenhouses), with co-financing provided by CIRAD (700 000 euros).

The architectural design of ARCAD and AbioPhen took account of environmental indicators, such as the management of water and waste, the use of low-impact materials, and energy efficiency.

Alternatives to chemical pesticides: 24 European research institutes undertake an ambitious roadmap

PRESS RELEASE - A strong demand from public authorities, agriculture professionals, and society in general, all over Europe, has spurred collaborative research in order to accelerate the agroecological transition. To face a challenge of this magnitude the joint declaration of intent “Towards a Chemical Pesticide-free Agriculture” aims to rethink the way research is carried out and develop new common research and experimentation strategies, not just at a national level, but throughout the whole continent. This declaration was signed today by 24 research organisations from 16 European countries. Driven by the French Institute INRAE and its German counterparts ZALF and JKI, this unprecedented endeavour has brought the European research community together around this ambitious vision of an agriculture free of chemical* pesticides. The declaration, formalised on 23 February at the Paris International Agricultural Show, with support of the french Mnistries in charge of Agriculture and Research, in presence of Amelie de Montchalin, The French State Secretary of EU Affairs, establishes a European research alliance, aiming to build a scientific roadmap that will soon be presented to the European Commission, as a contribution to the European Green Deal.

A new French-Chinese International Associated Laboratory dedicated to agroecology and green development

PRESS RELEASE - During the visit of a delegation from the China Agricultural University (CAU) to INRAE on 16 January 2020, INRAE’s Chair & CEO Philippe Mauguin and CAU’s Council President Peimin Jiang were the first to sign the agreement for the creation of a new International Associated Laboratory (LIA) dedicated to Agroecology and Agricultural Green Development (A-AGD).
This new LIA A-AGD aims to coordinate collaborative efforts between the CAU and French research institutes and universities. The goal is to achieve excellence in scientific research and support the transition towards a more sustainable and multiperformance model of agriculture, based on the principles of agroecology, both in the cereal plains of the north of China and in France.

Weed diversity mitigates crop yield losses

PRESS RELEASE - Scientists from INRA and the Scuola Superiore Sant’Anna (Italy) have shown that not all weed communities (spontaneous vegetation) generate crop yield losses, even in unweeded conditions, and that high weed diversity is associated to a reduced risk of important crop yield losses. Published in Nature Sustainability, these results provide new grounds for sustainable weed management.
